(2x+15)^(1/2)=x
We move all terms to the left:
(2x+15)^(1/2)-(x)=0
We add all the numbers together, and all the variables
(2x+15)^(+1/2)-x=0
We add all the numbers together, and all the variables
-1x+(2x+15)^(+1/2)=0
We multiply all the terms by the denominator
-1x*2)+(2x+1+15)^(=0
We add all the numbers together, and all the variables
-1x*2)+(2x+16)^(=0
We add all the numbers together, and all the variables
-1x*2)+(2x=0
Wy multiply elements
-2x^2=0
a = -2; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-2)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$x=\frac{-b}{2a}=\frac{0}{-4}=0$
